SC1LRUS Affinis, 

 was found abundantly in the woods of Singapore (on the occupa- 

 tion of that station by the British in 1819), agreeing with the two 

 former in having a flat nail on the very short thumb of the fore- 

 feet, but differing in colour, being of a cinereous grey or brown- 

 ish on the upper part of the head, body and tail, and on the out- 

 side of the limbs, and being nearly white on the under and inner 

 parts. It is about the size of the S. bicolor. The separation of 

 the colours on the body is not so abrupt as in that species, a stripe 

 of reddish-brown marking the transition. Grey is the most 

 usual colour of the upper parts ; but it appears to vary consi- 

 derably at different seasons (perhaps at rutting time), changing 

 to a light brown, and even to a dusky yellow. The first speci- 

 mens, that were procured in February, were of this latter colour ; 

 five months after they were found of a grey colour. One of 

 them, which has been in my possession about ten months, and is 

 now alive, has not changed colour perceptibly in that time. This 

 animal is remarkably tame, and has become a regular and very 

 amusing guest at the breakfast- table. 



A sufficient number of specimens of the S. maximus and bicolor 

 has not been examined, to decide whether they are subject to the 

 same variations of colour. A young one of the latter, procured 

 from the straits of Sunda, had the whole of the tail of the same 

 fulvous colour as the belly, while in adult ones it is entirely black, 

 like the upper part of the body. These facts indicate the neces- 

 sity of caution in multiplying the number of species in this genus 

 on mere diversities of colour, as intermediate varieties will often 

 be found to connect species apparently sufficiently remote. 



SCIURUS VlTTATUS, 



This species, which appears to be related to the Sciurus gingi- 

 nianus, is smaller than the preceding, and is frequent in the wood
